This coincidence is the more remarkable, as Coseguina had been dormant for twenty-six years: and Aconcagua most rarely shows any signs of action. It is difficult even to conjecture whether this coincidence was accidental, or shows some subterranean connection. Captain Fitz Roy being anxious that some bearings should be taken on the outer coast of Chiloe, it was planned that Mr.
It would undoubtedly be mistaken for an auk, when seen from a distance, either on the wing, or when diving and quietly swimming about the retired channels of Tierra del Fuego. San Carlos, Chiloe.

In the cases of great volcanic eruptions, as that of Coseguina, where torrents of rain fell at a time of the year most unusual for it, and "almost unprecedented in Central America," it is not difficult to understand that the volumes of vapour and clouds of ashes might have disturbed the atmospheric equilibrium.
There is thus no fundamental difference between the two types into which it is convenient to divide volcanoes." "In extreme examples of explosive volcanoes, the summit portion of a crater, perhaps several miles in circumference and several thousand feet high, is blown away. Such an occurrence is recorded in the case of the volcano Coseguina, Nicaragua, in 1835.
Nicaragua is also rich in volcanoes, being traversed its entire length by a remarkable chain of isolated volcanic cones, several of which are to some extent active. We have already told the story of the tremendous eruption of Coseguina in 1835, one of the most violent of modern times.

For the remarks on Guayaquil, see Silliman's Journ., vol. xxiv. p. 384. For those on Tacna by Mr. Hamilton, see Trans. of British Association, 1840. For those on Coseguina see Mr. Caldcleugh in Phil. Trans., 1835. In the former edition I collected several references on the coincidences between sudden falls in the barometer and earthquakes; and between earthquakes and meteors.
Hamilton see "Transactions of British Association" 1840. For those on Coseguina see Mr. Caldcleugh in "Philosophical Transactions" 1835.
If your map be of sufficient scale and moderately exact, you will find represented there two gigantic volcanoes, standing like warders at the entrance of this magnificent bay. That on the south is called Coseguina, memorable for its fearful eruption in 1835; that on the north is named Conchagua or Amapala, taller than Coseguina, but long extinct, and covered to its top with verdure.
